Mazizieh commented on issue #1659: Pagespeed Not optimising part of website images. URL: https://github.com/apache/incubator-pagespeed-ngx/issues/1659#issuecomment-513530171 > > Cache-Control: max-age=2592000 > > Cache-Control: no-cache > > You had 2 cache-control headers and I think the last is the one that are valid, so you had a Cache-Control: no-cache header and then pagespeed don´t rewrite these image. However, I have same thing for optimized images like below: ``` Request URL: https://www.example.com/media/banner/banner.jpg.pagespeed.ic.5oGh.webp Request Method: GET Status Code: 200 OK Remote Address: x.x.x.x:443 Referrer Policy: no-referrer-when-downgrade Cache-Control: max-age=31536000 Content-Length: 3870 Content-Type: image/webp Date: Sun, 21 Jul 2019 05:28:51 GMT ETag: W/"0" Expires: Mon, 20 Jul 2020 05:28:51 GMT Last-Modified: Sun, 21 Jul 2019 05:28:51 GMT Link: <https://www.example.com/media/banner/banner.jpg>; rel="canonical" nnCoection: close Server: nginx X-Original-Content-Length: 4569 X-Page-Speed: 1.13.35.2-0 Accept: image/webp,image/apng,image/*,*/*;q=0.8 Accept-Encoding: gzip, deflate, br Accept-Language: en-US,en;q=0.9 Cache-Control: no-cache Connection: keep-alive Cookie: _delighted_fst=1563107504455:{}; _gcl_au=1.1.1093713283.1563107505; __tawkuuid=e::www.example.com::bUuPtpau/D2XvbD3+w1kNoTUzNJBDUPN+TvnCz6O2JVQqEjXnSD4vmND53vu7fJi::2; _fbp=fb.1.1563107505426.1309377612; _ga=GA1.3.1080968892.1563107506; cto_lwid=f32d220d-e7dc-42f1-b675-0a3515469bb0; _scid=493ad801-c2a7-4000-9b04-7641d6def009; _delighted_lst=1563107508059:{%22token%22:%22SsYTjxsB5mMoCGZiVolmpIW6%22}; lang=en; frontend=gf874v5qkeoj2u3kqpj2gsqi04; seasonal=true; _gid=GA1.3.1305134949.1563620784; waitingroom=klYEg-TdSVB-8T2tL-ELD1r; __insp_wid=1702379826; __insp_nv=true; __insp_targlpu=aHR0cHM6Ly9zaG9wLmFkaWRhcy5hZS9lbi9tZW4%3D; __insp_targlpt=YWRpZGFzIE9ubGluZSBTaG9wcGluZyB8IFNwb3J0cyBDb2xsZWN0aW9uIHwgYWRpZGFzIFVBRQ%3D%3D; __insp_norec_sess=true; _sctr=1|1563656400000; _abvisitor=plpYPgBAgQAilWaT0WYUhsv51w4T3VDwjYBOfULB%3B1563693020; __insp_slim=1563693203809; TawkConnectionTime=0; _dc_gtm_UA-63988148-1=1; criteo_write_test=ChUIBBINbXlHb29nbGVSdGJJZBgBIAE; _gat_UA-63988148-1=1 Host: www.example.com Pragma: no-cache Referer: https://www.example.com/en/page1 User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/75.0.3770.100 Safari/537.36 ``` So, I don't think actually this is the problem, since this showing caching for both request and response from both user and server ends.
